Question 1

What SUP calculators are available on dincalculator.com?

Accepted Answer

dincalculator.com offers three free SUP calculators: a SUP board size calculator (volume, length, width by weight and style), a SUP paddle length calculator (by height and discipline), and an iSUP inflation pressure guide (correct PSI for board type, weight and temperature).

Question 2

How do I choose the right stand up paddleboard size?

Accepted Answer

Board volume should be at least your body weight in litres. Beginners typically need 1.4–2.0× their body weight in litres for stability. Board length and width depend on your paddling style: all-around boards suit most beginners, touring boards are longer for flatwater distance, and surf SUPs are shorter and more manoeuvrable.

Question 3

What PSI should I inflate my iSUP to?

Accepted Answer

Most 6-inch performance iSUPs work best at 14–16 PSI. Standard 4-inch boards work well at 12–14 PSI. Always check your board's label for the manufacturer's maximum rating. On hot days, inflate 1–2 PSI below maximum — air pressure rises as the board warms in direct sun.

Question 4

How long should my SUP paddle be?

Accepted Answer

The classic method: stand the paddle upright and raise one arm straight up — the handle should reach your raised wrist. In practice, add 20–25 cm to your height for all-around and touring paddling, 15 cm for surf, and 30 cm for racing. Adjustable paddles let you fine-tune length between disciplines.

Question 5

Are these SUP calculators free?

Accepted Answer

Yes. All SUP calculators on dincalculator.com are completely free to use with no account, registration, or subscription required.
